Combination food cooking oven with air impingement convection and microwave heating

摘要

A combination food cooking oven includes a fan 85 disposed in a fan box 72 to circulate heated air (heated by heater 87) between the fan box and the oven chamber via a baffle plate 74, at least one impingement air generator including a jet plate 150 (and/or 152) disposed in the oven chamber that converts a portion of the circulating air to impingement air that flows in a vertical direction within the oven chamber, and a microwave generator 126 to provide microwave energy into the oven chamber via at least one wall 80, 82 of the chamber. The oven includes a controller that operates the oven in the microwave mode, an impingement mode or a combination microwave and impingement mode. The jet plate is optionally removable from the oven so that the oven can be operated in a convection or combination microwave and convection mode.
